    Fix unused variable warning in sctp_output.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netinet/sctp_output.c:9367:33: error: variable 'cnt_thru' set but not used [-Werror,-Wunused-but-set-variable]
                int no_fragmentflg, bundle_at, cnt_thru;
                                               ^
    
    The 'cnt_thru' variable was in sctp_output.c when it was first added,
    but appears to have been a debugging aid that has never been used, so
    remove it.
